What we believe
Software should feel like a good friend: patient, honest and a little bit delightful. We sweat the details most teams skip, keep your data where it belongs, and ship products that make hard days easier.

Founder
Stella
Liao
Founder & Full-stack Product Engineer
I've spent six years taking SaaS products from a rough idea to production, across frontend, backend, APIs and infrastructure.
As CTO and lead engineer at Ternwheel, I scaled a platform that supports 1,000+ live tours: real-time venue coordination, Stripe billing and Unit banking integrations, an AI budgeting tool, and iOS and Android releases, while leading a small team. Before that, I spent nearly four years at Formation building internal tools, dashboards and customer-facing features end to end.
My path is a little unusual. I studied accounting and finance, taught myself to code, and went through Codesmith. That's why I love products that make complicated things feel simple. Pebble Bytes is where I build my own, starting with Crumpet.

How we work
Four quiet promises.
Privacy by default
We collect as little as possible and keep data on your device whenever we can.
Built for every brain
Dynamic Type, VoiceOver and plain language are part of the build, never an afterthought.
Honest pricing
No dark patterns. Free to start, long trials and one-time purchases where it makes sense.
Delight in the details
Sound, motion and words tuned until they feel just right.
Playground
Go on, play.
Grab the letters and toss them around. Click or tap empty space to drop a pebble.
